Show Notes

Recent space adventures by Richard Branson on Virgin Galactic and Jeff Bezos’ flight on his rocket ship, “New Shepard,” have lowered the bar for travel beyond earth’s atmosphere.

One consequence of humans entering space is the burgeoning and exciting field of space medicine. William Tarver, MD, MPH, discussed astronaut selection and the challenges of space flight with me in Episode #35: https://www.youtube.com/watch?v=eCGqeSkqVx8&t=39s

Today, I’m joined by Karina Marshall-Goebel, Ph.D., to discuss health issues related to long-duration spaceflight. Dr. Goebel is a human physiologist with special training and ten years of experience in space medicine. As human beings venture further into space, health concerns related to long-duration space flight will inevitably increase. A round trip to Mars will be a 3-year journey, and some health issues like bone and muscle loss and exposure to radiation are foreseeable. But no one can yet predict all hazards to human health that must be addressed along the way.

One recently described health issue that affects approximately 2/3 of the International Space Station crew is spaceflight-associated neuro-ocular syndrome (SANS). Astronauts may experience visual blurring as their eyeballs become distorted over time. Other, more subtle ocular effects such as retinal and optic nerve changes occur. The underlying cause seems to be an excessive amount of fluid that has shifted to the head that would normally be held lower in the body due to gravity. To learn more about this syndrome and devise preventive measures and treatments, astronauts currently study themselves while in space with ultrasound and eye examinations.

Dr. Marshall-Goebel discussed countermeasures under development that astronauts could employ to counteract health problems associated with microgravity fluid shifts. Artificial gravity is one solution but tough to implement. A novel solution might be “vacuum pants,” which redistributes excess fluids from the upper body back to where they belong.
